ENGINE MAINTENANCE
■ Replace Spark Plugs_
Remove and replace spark plugs (Champion
RC12YC) every 100 operating hours or once
annually, whichever comes first. See ENGINE
SPECIFICATIONS for recommended sparkplugs.
Set gap on plugs to 0.76mm.
A
CAUTION! DO NOT blast dean spark plugs.
Clean with pen knife or wire brush and sol¬
vent.
■ Check Engine Oil Level_
Check engine crankcase oil level frequently (prior to
each use or at least every eight hours of operation).
See Page 5 for recommended oils. Rest unit on a
level surface and remove dipstick from extended oil fill
tube. Wipe dipstick dry and reinstall all the way into
the oil fill tube. Again remove dipstick. Oil should be at
dipstick FULL mark. Add oil as necessary. DO NOT
OVERFILL ABOVE "FULL" MARK.
■ Changing Oil and Oil Filter_
Change oil after the first eight hours of operation.
Thereafter, change oil every 50 operating hours under
normal conditions. If engine is operated under heavy
load or in high ambient temperatures, change oil
every 25 hours of operation. Drain oil from oil drain
plug while engine is still warm from running.
Change engine oil filter every 100 hours of operation
(every second oil change). Before installing new filter,
lightly lubricate filter gasket with fresh, clean engine
oil. Screw new filter on by hand until gasket contacts
the filter adapter. Then tighten about 3/4 turn further.
Start and run engine for about 30 seconds, then shut
down. Recheck oil level and add oil as necessary.
Finally, start engine and check for leaks. See figure
12 below for location of oil filter and oil drain plug.

aged if you run it using a dirty air cleaner. Clean or
replace foam pre-cleaner every 25 hours of operation.

annually, whichever comes first. Clean or replace
more often if operating under dusty or dirty condi¬
tions.
